求帮助计算下列货币的远期套算汇率。 汇水点数前小后大为远期升水，前大后小为远期贴水远期：USD/DEM=（1.6220-0.0176）/（1.6230-0.0171）=1.6044/1.6059远期：USD/JPY=（108.60+0.10）/（108.80+0.78）=108.70/109.58远期：DEM/JPY=（108.70/1.605.
计算下列各种货币的远期交叉汇率~ CHF/USD=(1/1.5480)/(1/1.5460)=0.6460/0.6468CHF/CNY=(8.1080/1.5480)/(8.1090/1.5460)=5.2377/5.2451CHF/GBP=[1/(1.6450*1.5480)]/[1/(1.6430*1.5460)]=0.3927/0.3937CHF/EUR=[1/(1.1040*1.5480)]/[1/(1.1030*1.5460)]=0.5851/0.5864CHF/JPY=(118.20/1.5480)/(118.30/1.5460)=76.36/76.52
